APPARATUS FOR REAMING SMOKING PIPES.

Application led November 30, 1927. Serial No. 236,639.

This invention pertains to reaming devices and more particularly to apparatus for reaming smoking pipes.

One of the objects of this invention is to provide a device which may be installed in a convenient location, in a cigar store or similar place convenient to smokers, and which may be used to ream out the burnt incrustation in the bowl of a smoking pipe in a convenient and simple manner.

Another object is to provide such a device, which may be easily and quickly adjusted to ream any size of pipe.

Another object is to provide such a device which will not only ream the bowl, but by which a suitable chamfer may be applied to the upper edge of the bowl.

Another object is to provide such a reaming device in combination with a suitable receptacle for receivingr the cuttings, so as to prevent their being scattered about the place.

Further objects will appear from the fol lowing description, taken in connection with the accompanying drawing, in which- Figure l is a vertical section of a reaming device embodying this invention;

Figure 2 is a plan view of Figure 1, with the cover removed. In this figure, the Shanks of the reamers are shown as cut off so as to show the construction of other parts.

Figure 3 is a detail section on line 3 3 of Figure 1.

Referring to the accompanying drawing, 1 designates a bracket which may be arranged for attachment to the wall, as indicated at 2, and which provides a support for the apparatus. Mounted on the support 1 is a vertical bearing 3, in which is mounted for rotation a vertical shaft 4. This shaft has fixed to its lower end a bevel gear 5 meshing with a corresponding gear 6 on a cross shaft 7 journaled in the support 1. The shaft 7 has secured to the other end thereof an operating crank 8. By turning the crank 8, the shaft 4 may be driven through the agency of the gears 5 and 6.

The upper part of the support 1 is formed to provide a housing 9. Vithin this housing there is fixed to the shaft 4 a gear 10. Loosely mounted on the shaft 4 and above the gear 10 isa turret 11. The turret 11 may be formed of sheet metal, as shown in the drawings. A hub 12 is fixed to the middle thereof, while at spaced points around its periphery the sheet is cut radially and portions thereof bent downwardly to provide ears 13. The turret is held in place on the .shaft 4 by a collar 14 secured by a set screw 15 or other suitable fastening.

Pivoted on screws 16 threaded into the ears 13, is a series of bearing blocks 17. The blocks 17 are spaced around the periphery of the turret 11 and are arranged to pivot on the screws 16 so that they may be turned to different positions thereon. J ournaled in each of the bearing blocks 17 is a reamer 18. Fixed to the shank of each realner 18 is a pinion 19.

The housing 9 is provided at one point in its periphery with a gate or door 20. Vithin this door-way, there is located in the bottom of the housing 9 a guide socket 21. The parts are so proportioned that the turret l1 may be turned upon the shaft 4 until a reamer 18 of the desired size is brought opposite the door 20. This reamer may then be swung downwardly through the door on the pivot screws 16 until its shank engages the socket 21. In this position the pinion 19 will establish driving connections with the gear 10. A keeper 22 is pivoted at 23 on the bottom of the housing 19 and is arranged to swing on said pivot, so as to engage the shank of the reamer 18 positioned in the socket 21. In this position, the keeper 22 completes the guide 21 so as to form, in effect, a bearing for the reamer shank. The keeper 22 is held in place by a spring latch 24.

The support 1 extends downwardly and has formed or mounted thereon a bowl or receiver 25 adapted to receive the cuttings. A cover 26 may be provided for the housing 9 so as to enclose those reamers which are in idle position.

In the use of this device, the smoker selects a reamer 18 of the proper size to fit his pipe, moves the turret 11 around so as to bring that reamer opposite the gate 2O and then swings the reamer downwardly from idle position to roaming position, with its cutting end extending downwardly and its shank engaged in the socket 21. During this movement, the reamer turns with the bearing block 17, which pivots on the screws 16. At the completion of the movement, the pinion 19 establishes driving connections with the gear 10. The operator then swings the keeper 22 into position until it latches at the latch 24. By now operating the crank 8, the shaft 4 will be driven, as preg viously described, and will, in turn, through the agency of the gear 10 and the pinion 19, drive the reamer. The operator noW brings his pipe into engagement With the loWer end ot the reamer, which will operate to cut out '1e incrustation in the boivl to any extent der (lne, ot the reamers is provided with i. chanrtering head Q?, so that when the reaming oi the bowl is completed, this reamer may be nronght into operative position and a suitable chamter cut en the inner upper edge ot the pipe bowl. The operator knocks out the outings Ytrein his pipe into the bowl 25.

it will be seen that this invention provides a simple and elleetive means tor cleaning ont smoking pipes. An assortment ot reamers oi' arious to tit any size of pipe is mounted in the turret and ready to be swung to rea1n ing position by a simple operation. Viren in that position, the reamer is securely locked and held in operative relation with the driving mechanism connected to the crank 8. The reaming taires place by a simple movement ot' the crank, while holding' the pipe in engage-- ment with the reamer. The bovvl lo provides convenient receptacle for receiving the cuttings.

It is obvious that various changes may be made, Within the scope oi' the appended claims, in details ot construction without departing from the spirit oi this invention. 1t is, therefore, to be understood that this invention is not limited to the specitic details shown and described.

Having thus described the invention, what is claimed is:
